QUESTIONS Can circuit class therapy provide sufficient exercise dosage (at least 20 minutes at ≥ 50% heart rate reserve or total caloric expenditure ≥ 300 kilocalories) to induce a cardiorespiratory fitness effect in adults with traumatic brain injury? Can feedback from heart rate monitors influence exercise intensity? DESIGN Randomised controlled trial within an observational study. PARTIC...

After infecting a CD4 T cell, Human Immunodeficiency Virus (HIV) can either replicate and kill the cell or enter latency, a dormant state of the virus where viral gene-expression is turned OFF. This cell fate decision between viral replication and latency is controlled by the viral regulatory protein, Tat. This protein is known to activate its own production, creating a positive feedback circui...

The IL-6/STAT3/NF-κB positive feedback loop links inflammation to cancer and maintains cells at a transformed state. Similarly, cancer-associated myofibroblats remains active even in absence of cancer cells. However, the molecular basis of this sustained active state remains elusive. We have shown here that breast cancer cells and IL-6 persistently activate breast stromal fibroblasts through th...

background: mediodorsal (md) thalamic nucleus, which is considered to take place between extra pyramidal and limbic feedback circuit, receives projective fibers from ventrolateral neurons of reticular part of substantia nigra (snr). in order to better understand the influence and chemical reaction of these fibers upon md nucleus, the morphology and synaptology of them were examined in the prese...

This paper demonstrates the equivalence between simple feedback loops and the biochemical enzyme reactions in confined media that obey Michaelis-Menten kinetics. Single and cascaded reactions are modeled, and general principles to achieve enzyme transfer functions are set out. Reaction rate and concentration difference are identified as the through and across variables of biochemical networks, ...

This paper describes the design of a bandgap reference, implemented in 32 nm FinFET technology. The paper introduced new method for increasing stability of output voltage of bandgap circuit. In the proposed architecture extra feedback is used for setting the output voltage in fixed voltage. This feedback makesbandgap circuit more stable and speedy employing back gate biasing of the FinFET devic...
